Answer to Question #178944 in Calculus for John withers

Question

Find the work done pulling a sled 75𝑚 with a 70𝑁 force if the handle makes an angle of 36° with the ground. 

Answer 1

Ans:

Given $F=70N$ $S=75m$ Angle between them is $36\degree$

We know that

Work done by this force will be

$W=F\times S\times Cos36\degree$

$=70\times 75\times0.8090$

$=4247.25J$
